Marble Madness!!

This week the girls had a super open activity creating marble runs. Their goal was to get marbles from the top of a chair down to the bottom while staying in a chute made of recycled materials that we all brought in.


Then we had them design their marble chute beforehand so that they could go through the process of making a plan and trying to carry it out.


Some did and some didn’t, but they all created beautiful masterpieces that moved their marbles marvelously.

Windmill Wind-up!

Last week we had the girls construct their own windmills! It is one of our favorite activities and the girls were so creative! First we talked about the word “Energy” and wind and looked at different pictures of windmills to get a sense of what we wanted to do.


They were really cute and wanted to try out a bunch of different shapes like stars and hearts. It took a little while to get the right shapes and sizes of the blades, but eventually some people got it.

We brought in a pretty strong fan for them to try and make their windmills spin with. Not everyone got it, but a few girls did. They came up with some pretty neat designs and learned some things along the way.


Afterwards we recapped what had worked and what hadn’t with the construction of the windmills and I think we have some little engineers in the making!

Make Those Pennies Shine!

This week we further explored chemistry and chemical reactions by cleaning pennies! We went over “Reactions”, which was our word last week, and learned about our new word “Element”.


This is a part of our new push to work on literacy with the girls. Each week we pick a word, discuss it, and have each of the girls write the word on a sheet of paper and we’re making a book. We’re also going to make a word wall to put up and have been bringing in books. It was so adorable. The girls got really excited about writing the word. They even wanted to write words from previous weeks, so hopefully we’ll start connecting activities!

The pennies were so adorable. They tried out cleaning pennies with water, soapy water, and vinegar and salt.


After a few minutes, it was pretty clear that vinegar and salt worked best. The pennies became so shiny. It was really impressive and we could actually draw on the pennies. We also left them out on a paper towel with vinegar and salt and they eventually turned green! It’s the same reaction that turned the statue of liberty green. I think both girls and mentors had a wonderful time!

Balloon Blow-Up Bonanza!!

The girls had a blast today blowing up every balloon in the building! We taught them about chemical reactions using the classic baking soda + vinegar reaction, which bubbles and creates gas. They did such an awesome job! First we just had them add vinegar to a big bottle and baking soda into the balloon.

Then they had to put the balloon on the bottle to let it fall down into the vinegar and time how long it took for the balloon to blow up.

Some of them got really excited about how big the balloons got. Then we had them try it with different amounts of vinegar and baking soda as well as different sized bottles and see what made the balloon blow up faster.

They absolutely loved this part and all of them did as many balloons as possible. Some of them walked out with handfuls of bottles with balloons attached.


They really got into it and understood what a chemical reaction was. They also loved a video we showed with a whole bunch of awesome chemistry reactions. I hope we made some future chemists!!
